Prior to Red Hat Storage 4, Ceph storage administrators have not had access to built-in RBD performance monitoring and metrics gathering tools. While a storage administrator could monitor high-level cluster or OSD I/O metrics, oftentimes this was too coarse-grained to determine the source of noisy neighbor workloads running on top of RBD images. The best available workaround, assuming the storage administrator had access to all client nodes, was to poll the metrics from the client nodes via some kind of homegrown makeshift external tooling…阅读全文

The landscape of modern IT infrastructure is dominated by software defined networking, public cloud, hybrid cloud and software defined storage. The shift from legacy hardware centric architectures to embrace software defined infrastructure requires a more mature orchestration "engine" to manage changes across distributed systems…阅读全文

However, getting started with Ceph has typically required the administrator learning automation products like Ansible first. While learning Ansible brings its own rewards, wouldn’t it be great if you could simply skip this step and just get on with learning and using Ceph…阅读全文
